The pins feel really nice when holding them. I do like the colors on the pins as they look very vibrant, which really makes the designs on the pin stand out.
I did have a bit of trouble getting the Pinfinity AR app to pickup the pins for the AR. I did find a way to make the app to pickup the pin. You have to have the camera pointed at the center of the pin and start really close and slowly pull away until the pin comes into focus. The app will be able to scan the pin.
